REVERSING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 560,036, dated May 12,1896.

Application filed October 30, 1895. Serial No. 567,848. No modelfl Toall whom it may concern:

Be it known that I, GEORGE F. HUTCHINS, a citizen of the United States,residing at \Vorcester, in the county of IVorcester and State ofMassachusetts, have invented certain new and useful Improvements inReversing Mechanism for Looms, of which the following is aspecification.

My invention relates to looms, and particularly to reversing mechanismfor looms; and the object of my invention is to provide means toautomatically operate the reversing mechanism shown and described in myLetters Patent of the United States No. 491,776, of February 14, 1893.

My improvements for automatically operating said reversing mechanism aredesigned particularly for heavy looms, in which considerable power isnecessary to move the lay to its rear position when the loom is stopped.

My invention consists in certain novel features of construction andoperation of my mechanism for automatically operating said patentedreversing n1echanism,as will be hereinafterfullydescribed,and the naturethereof indicated by the claims.

Referring to the drawings, Figure 1 is an end view, looking in thedirection of arrow a, Fig. 2, of a loom of ordinary constructionprovided with the reversing mechanism described in said patent and mymechanism for automatically operating said mechanism combined therewith.The shuttle-boxes and operating mechanism are not shown. Fig. 2 is asectional plan view of portions of the loom shown in Fig. 1, taken online 2 2, said figure, looking in the direction of arrow 6. Fig. 3 is aside view of the filling or weft stop-motion. Fig. 4 is a plan view ofthe parts shown in Fig. 3, looking in the direction of arrow 0. Figs. 3and 4 are shown on an enlarged scale; and Fig. 5 is a sectional viewtaken at a point indicated by line 5 5, Fig. 2, looking in the directionof arrow d, same figure.

In the accompanying drawings, 1 is the loom side; 2, the lay; 3, thecrank-shaft; 4, the bottom shaft; 5, the pulley-shaft; 6, thepulley-frame; 7, the friction-pulley, provided with a friction-face 7with which the drivingpulley Sis moved into or out of contact to startor stop the loom by the ordinary shipping mechanism shown and describedin my United States Letters Patent No. 437,894.

Combined with the friction-pulley 7 and driving-pulley 8 is thereversing mechanism above referred to, fully shown and described inLetters Patent No. 491,776, above men= tioned, to which reference ishereby made.

The lever 9 of the reversing mechanism is hung on a stud 9' in thepulley-frame 6 and operates the reversing mechanism, as described insaid Patent No. 401,776, except that at certain periods, to behereinafter described, said reversing mechanism is automaticallyoperated by my mechanism combined therewith.

A beveled gear 10 is fast on the pulleyshaft 5 and drives a largebeveled gear 11 fast on the bottom shaft 4. The beveled gear 11 mesheswith and drives a gear 12 fast on the crank-shaft 3 in the ordinary way.A connector 13 connects the crank 3 and the crank-shaft 3 with the lay2, the lay-sword 2 of which is pivoted at its lower end on a pin 14 inthe lower part of the frame 1 in the usual manner. In front of the lay2, secured in the usual way, is a protector-rod 15, fast upon which ateach end of the loom is the binder-finger 16 and the protector-dagger 17It will be understood that the binderfinger 16 is adapted to bearagainstthe shuttle-binder of the shuttle-box, (not shown,) and if theshuttle is not properly boxed in the operation of the loom the binderwill hold the finger 16 out and cause the dagger 17 to strike theknock-off lever 19 and stop the loom in the usual way.

In Figs. 3 and 4 are shown, on an enlarged scale, a side and plan viewof the filling or weft stop-motion, which is of substantially the sameconstruction and operation as the weft stop-motion shown and describedin United States Letters Patent No. 321,226, of June 30, 1885, to whichreference is made. Referring to said Figs. 3 and 4, 18 is thebreast-beam, under which extends the knockoff rod 20, which has bearingsin the ends of the loom in the usual way. 46 is a finger or armprojecting from a collar 47, secured on the knock-off rod by a set-screw48. A stand 49 is secured to the rear face of the breast-beam 18 andextends inwardly and has a knock-off arm or finger 50, pivoted at oneend on a stud 51 at the lower end of said stand 49 and provided with aknob or projection 50, adapted to rest on the finger e6. Secured to thehorizontally-projecting end of the stand 49 by a bolt 52 is a shoe ortrack 53, on which is adapted to rest and travel, as the lay moves, thehorizontal bent end 54 of the dagger i, which is pivoted at its innerend on a bolt 55 in the lower end of the stand 56, bolted to the lay 2.A connecting-rod 57 is pivoted at one end to the dagger 54 and at itsother end to the crank-arm 58 on the shaft 59, which has hearings insaid stand 56 at the front of the lay. The shaft 59 carries the feelers60, secured thereto by a hub 61 and set screws 62. The feelers 60 extendover a transverse slot 63 cutin the top of the lay, and in case they arenot held up by the filling or weft they will drop into said slot toautomatically stop the loom by means of the filling stop-motion abovedescribed, for the forward motion of the lay will cause the end 5i ofthe dagger 51, which is dropped by the lowered position of the feelers60, to strike against the end of the arm or finger 50 and force downsaid arm and cause the stud 50 thereon to move back the finger 46 on theknock-off rod and revolve said rod to stop the loom in the well-knownway and automatically operate my reverse mechanism, as will behereinafter described.

I will now proceed to describe the construction and operation of mysupplemental mechanism combined with said patented reverse mechanism toautomatically operate the same.

A stand or frame 21 is secured to the loom side 1 by bolts 22 andcontains the rubberlounter pocket 21, in which is secured the rubberbunter 22. Hung on a stud 23 in the lower part of the frame 21 (seeFig. 1) is the angle-lever 24, which is connected to the lever 9 of thereverse mechanism by the rod 25, which extends at its upper end looselythrough a hub 21 on one end of said lever 24. The other end of the rod25 is pivotally attached at 9 to the front end of the lever 9. Anexpansible spiral spring 46 is mounted on the rod 25, and bears at itsupper end against the hub 21 of the lever 2i, and at its lower endagainst a collar-26 on the rod 25. The spring 16 is of sufiicienttension to communicate motion from the angle-lever 21 to the lever 9,and thus furnishes a yielding connection between said lever 21 and lever9, and not a rigid connection.

Attached to the inside of the frame 21 by bolts 21 is a sliding frame27, which is provided with a projection or lug 27, (see Fig. 2,) whichextends in front of and in contact with the rubber bunter 22. Said frame27 at its front upper portion is provided with a hub 27, in which ismounted a shaft 28, on which a dagger 29 is loosely supported at oneend, to move independently of said shaft. The hub 30 of a finger 30 isfast on the shaft 28, and

said finger 30 extends under the dagger 29 and acts to raise said daggerat the proper time. The inner end of an arm 3 is fast on the knock-offrod 20. Said arm carries a stud 33, to which one end of the connector 31is attached. The other end of said connector 3% is attached to a stud 31in the hub 31, which is fast on the shaft 28. The arm 32 is alsoprovided with a rearwardly-extendin g forked end 32, (see dotted lines,1, and also Fig. 5,) which is pivotally attached to a stud 35 in finger35, loose on shipper-rod 36, which is provided with the shipper-handle37, carrying the auxiliary handle 38 hung thereon. A connector 3tconnects the auxiliary handle 38 with the finger 39, hung on a pin 40,fast in the stand 40. The finger 39 has a face 39, which is in contactwith the outer end of the knock-off lever 19, so that when the operatorgrasps the auxiliary handle 38, in connection with the shipper-handle37, to start the 100111 the knock-off lever 19 will swing its inner endagainst the finger 35, loose on a shipper rod 36, and cause the dagger29, through forked end 32, arm 32, and connector 3i, to be raised out ofthe path of the block 11, which is fast on the lay 2, as the lay heatsup. After the first pick of the lay the filling will be under thefceler-wires and hold said wires up in the usual way to prevent theoperation of the stop filling motion and the engagement of the dagger 29with the block 11. A pin 42 is secured in a slot 42 in the inner end ofthe sliding frame 27, (see Fig. 1,) and as said frame 27 moves forwardthe pin 42 will engage the anglelever 2i and move said lever forward tocommunicate motion, through spring l6, to the lever 9 of the re versemechanism. The pin 42 also acts as a stop to limit the backward motionof the lever 21 when released by the pawl In the stationary frame 21 issecured a stud 43, on which is hung a pawl -13. A spring e3" (see Fig.2) is coiled around said stud i3, and acts to cause the pawl to engagethe teeth or notches 24: in the upper end of the upright arm of theangle-lever 2a, to hold said lever in its forward position on the returnof the sliding frame 21. The pawl 13 has a rearward extension or heelit-3", which will be en gaged by the end of the arm 44, secured upon theunder side of the lay, upon the rearward motion of the lay, to disengagethe pawl 5L3 from the teeth or notches 24: in the upper end of the lever2i, and allow said lever to return to its upright position. (Shown inFig. 1.)

From the above description, in connection with the drawings, theautomatic operation of the reverse mechanism on the breaking of thefilling, and the operation of the filling stop-motion mechanism, will bereadily understood by those skilled in the art.

The operation of the filling stop motion (shown in Figs. 3 and 4) causesthe knock-off rod 20 to rotate, and through finger 35, operated byforked arm 32, the knockoff lever 19 to operate to move the shipper-rod36 and step IIO the loom on the forward beat of the lay in the usualway.

The rotation of the knock-off rod in the operation of stopping the loomallows the dagger 29 to drop down, the lifter-finger 30 being lowered bythe rotation of the shaft 28, through connector 3% and arm 32, so thatas the laymoves forward the block 41 will engage the end of the dagger29 and cause the sliding frame 27 to move forward and compress thebunter 22, and the pin 42 on said frame 27 will engage the angle-lever2i, and rock said lever 2i on its pivot-pin 23, and through the spring46 move down the front end of the lever 9 and bring into action thereverse mechanism mounted at the opposite end of said lever, to causesaid reverse mechanism to operate, as set out in said Patent No. 491,7 76, and move the lay to its rear position, as shown in Fig. 1. v

The forward motion of the lay will release the pawl 4:3 from the arm 44and allow said pawl to engage the teeth 2st in the upper end of lever 2iand hold said lever in its forward position to operate the reversemechanism, while the sliding frame 27, by the expansion of the hunter22, will return to its rear position immediately as the lay starts tomove back. The continued backward movement of the lay causes the arm telto engage the heel of the pawl 43 and disengage said pawl from the teethin the lever 24, as above described, to allow said lever to return toits upright position through the action of a spring 4.5.

It will be understood that the forward movement of the sliding frame 27is very slight, but is still sufficient to communicate, throughangle-lever 24; and spring 46 on the rod 25, suflicient movement to thefront end of the lever 9 to bring into operation the reverse mechanismsupported on said lever.

The advantages of automatically operating my patented reverse mechanismwill be readily appreciated by those skilled in the art.

It will be understood that the details of construction of some of theparts of the mechanism for automatically operating the reverse mechanismmay be varied if desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1.
